Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a continuous automatic blending device for multi-liquid dyes, and more particularly to an improvement in a blending device for liquid blended dyes used during dope coloring and spinning of synthetic fibers.

The conventional method of mixing dyes, etc. has been to mix several types of primary color dyes that make up the components of a desired color with the amount of experimental music corresponding to the desired color sample. An extremely high level of experience and skill is required for its formulation. In addition, in the above-mentioned blending by experts, there is often excess blending of more than the desired amount, and blended dyes made by mixing multiple liquid dyes are left untreated after being blended in advance. These blended dyes have various problems such as generation of dye scale and change in color tone due to changes over time. Therefore, immediately before using the mixed dye, it is necessary to mix the above-mentioned plurality of primary color liquid dyes to make the mixed dye, and the blending ratio of such dyes requires high precision. The working environment for manually performing the above-mentioned high-precision blending work is poor, and the work may not be able to be carried out satisfactorily.

SUMMARY OF THE INVENTION An object of the present invention is to provide a continuous automatic blending device for multi-component dyes that overcomes the various problems and drawbacks mentioned above.

Still another object of the present invention is to provide a dye tank containing a plurality of dyes, to control and mix the discharge amount of each tank according to a predetermined program, and to adjust the blended dye solution to a predetermined level as needed. An object of the present invention is to provide a continuous automatic blending device for multi-component dyes, which is equipped with a means for checking and giving feedback on whether the blending amount is correct using a system consisting of an automatic sampling device, a colorimeter, and a data processing device (computer).

In order to achieve the above-mentioned object, the present invention specifically provides an opening/closing pulp member provided at the outlet of a plurality of dye tanks each containing different liquid primary color dyes, and each opening/closing pulp member being connected to a measuring machine through a weighing machine. It has a control mechanism for opening and closing the tank according to predetermined set values, and a mixing tank for receiving and mixing needle-like solvent into the dye solution in each dye tank to form a blended dye. This is a continuous automatic blending device for multi-component dyes, which is capable of continuously supplying a blended dye solution when used.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The continuous automatic blending apparatus for multi-component dyes according to the present invention will be described in detail below with reference to one embodiment shown in the drawings.

To explain the operation, the dye stock solution in the dye stock solution container Q' is opened by the electric pulp (4n)'r, and the stock solution dye delivery pump (14)
By driving the dye stock solution container α, the dye stock solution is sucked up and placed in the Y dye head tank (1). In the same way, R liquid and B liquid are also sucked up from the dye stock solution container (not shown) and transferred to the R dye head tank (2) and B liquid.
A suitable needle is held in the dye head tank (3).

In the case of an actual device, 3 to 40 dye head tanks are used to cope with diversification of colors. When trying to blend a multi-component dye from this state, electric pulp (4a), (4b), (4c) is used depending on the desired blending amount.
according to predetermined set values, the weighing machine (7) and the control device -
The opening and closing operations are performed under the control of , and the undiluted dye is allowed to flow down into the measuring tank (5), and six liquids having the same set blending amount are supplied. The measured undiluted dye is released by opening the electric valve (4e).
Directions (1) to the designated dye liquid mixing tank (9a) or (9)
b). When all the stock dyes have been measured, the electric valve (4d) opens and the organic solvent (acetone) tank opens.■
The organic solvent cleaning liquid pumped by the organic solvent pump a9 is jetted out through the measuring tank cleaning shower (8), and a predetermined flow rate is applied to the measuring tank (5) while cleaning the inside of the measuring tank (5) and the conduit. It is measured in c) and allowed to flow down into the dye liquor mixing tank (9a). In addition, since the inside of the weighing tank (5) is cleaned with an organic solvent, the top lid (6) of the weighing tank is installed in consideration of the working environment, and the seal with the weighing tank (5) is made using a sealing liquid (silicon oil). Sealing is done with α scratches. Further, the solvent vapor generated inside the metering tank is led to the solvent recovery tower O through piping and is treated therein.

The undiluted dye and organic solvent supplied to the dye liquor mixing tank (9a) are driven by the Not stirring blade (10a) and the Not stirring electric motor (tta) for the time set by the timer (control device). , the above dye and an organic solvent are stirred and mixed. The blended dye thus stirred and completed is sent to the synthetic fiber stock solution coloring and spinning process O by opening the electric valve (4j) and passing through the four-force switch a3, where it is mixed with the spinning stock solution (dope) and spun. Colored fibers are produced.

The liquor vapor generated during the reception of the organic solvent in the dye liquor mixing tanks (9a) and (9b) is led to the solvent recovery tower 0 via piping and is treated therein.

The blended dye stays in the Nol dye liquor mixing tank (9a), while the NO2 dye liquor mixing tank (9b) is transferred to the Nol dye liquor mixing tank (9a).
Make a mixed dye using the same procedure as when preparing it.N.

1 When the mixed dye solution in the dye solution mixing tank (9a) is empty, the 4-way switching valve α1 is activated, and the NO2 dye solution mixing tank (9b) is activated.
At the same time, start feeding the new blended dye to the coloring and spinning process 0, and remove the remaining liquid in the No. 1 dye solution mixing tank (9a) by opening the electric pulp (4 m) and emptying it into the waste dye container ( C)
discharged inside. In addition, in order to completely wash the remaining dye solution in the Nol dye solution mixing tank (9a), pressurized pure water is pumped from the pure water tank to the cleaning solution feed pump 0Q using the electric valve (4g) using the timer. ), open the Not cleaning nozzle (22a
) to clean the entire tank and drain it into the waste dye container (g). For secondary cleaning, acetone tank [available]
From there, a fixed amount of solvent is jetted out from the No. 1 solvent cleaning nozzle (28a) through the organic solvent delivery pump a$ and flowmeter QD to perform cleaning, and the waste dye liquid is discharged into the waste dye container (g) to complete the cleaning process. At that point, the electric valve (4j), (4m)
Close and prepare to receive the next batch of dyestuffs. By repeating this series of cycles 1NO1 mixing tank (9a) and Na3 mixing tank (9b), the blended dye can be continuously supplied.

As detailed above, the continuous automatic blending device for multi-component dyes according to the present invention automatically weighs one or more types of dyes, and also stirs, discharges, and washes the weighed dyes and six organic agents. By automating the entire cycle, it is possible to continuously obtain a blended dye solution, and furthermore, the complete automation has the effect of greatly contributing to improving the working environment and saving labor.
